The Wisconsin Department of Public Instruction released scoring data for Wisconsin schools and districts in the 2012-13 school year. Here is a list of the schools that failed to achieve the state's expectations:

Baltimore City Schools scheduled a press conference for Tuesday morning to make what was termed a major announcement.

Thornton was selected by a search committee in January 2010 to lead Milwaukee Public Schools. He won the job by a unanimous vote of the Milwaukee School Board. His contract was recently extended through June 2016.

He faced several challenges in Milwaukee, most notably serving a student body that lived in poverty. According to the 2010 U.S. Census, 41 percent of children within the district lived below the poverty line, and more than 80 percent of students qualified for free or reduced-price lunch during the 2012-2013 school year.

Thornton also dealt with schools in the district that failed to meet the state's criteria for a successful school. Several low-performing schools were closed under Thornton's watch in Milwaukee.

Milwaukee Public Schools have about 79,000 students. Baltimore reports it has around 84,000 public school students.

Bonds told Wainscott that he had heard that Baltimore had expressed interest in Thornton, but he had no idea whether he had been offered a job.

If Thornton were to leave, Bond said, "His leaving would be a drastic loss for MPS and for Milwaukee."

"No matter what the future holds we're in a position to keep going. Obviously, nobody wants to deal with a transition in the middle of the school year or in the beginning of a budget season, but at the same time, we have to thank Dr Thornton. He's put us in a really good place," Milwaukee School Board member Meagan Holman said.

The Baltimore City Board of School Commissioners said it will announce "an important milestone for Baltimore City Public Schools" on Tuesday morning.

Milwaukee Teachers' Education Association President Bob Peterson issued a statement late Monday afternoon saying they wanted to acknowledge Thornton's years of service in Milwaukee and that they look forward to working with the school board to find a new superintendent.

"A quality superintendent is essential to the district’s future. MPS is the only educational institution in Milwaukee with the capacity, commitment, and legal obligation to educate all children.

Prior to coming to Milwaukee, Thornton was superintendent in Chester, Penn., and an academic officer in Philadelphia.
